Application illed'llecember 9, 1912. Serial No. 735,682.

To all whom it may concern Be it known that I, loHN EDWARD Wnicnr, a citizen of the United-States, re-

siding at Pittsburgh, in the county of Allegheny and Sta'te of Pennsylvania, have invented certain new and useful Improvements in Printing-Telegraphs, o'f which the following is a full, clear, and exact description.

The improvements constituting the invention which forms the subjectmmatter Aof this application, are embodied in a combination of mechanisms capable ofindependent operation or control, but cooperatively related and adapted to print in column form upon a sheet of paper, letters and characters corresponding to definite combinations of electrical impulses transmitted over a telegraph line, and to effect the spacin ,paper feed and other operations necessary or such purpose y and usually performed by a unitary device known as a printing telegraph receiver or machine.

The primary object of my invention is, in general,4 to provide a printing mechanism capable of rapid and accurate response to current impulses transmitted over long circuits where the line conditions are suchas to materially, and often seriously limit the speed and efficiency of the instruments heretofore devised and used for this purpose, but

fas

in the attainmentl of this object I have 1nvented and devised features which not only contribute to the more eflieient operation of the particular system of which this instrument constitutes a member, but which are also distinctive in themselves as novel and useful elements in telegraphic printing and signaling machines in general.'

My improved.instrmnent contains means for supporting a sheet of paper of indefinite length,and a type wheel in the form of an elongated cylinder having a plurality of rows of letters and characters arranged, in the present instance, in ten vertical columns, and comprise-s as its more essential elements, novel in construction andfunction, electrically actuated devices capable of independent and non-interfering and hence simultaneous operation and control which may be generally defined as follows: (l) Mechanism for turning' a type. wheel to bringanyone of, say,.the odd numbered character columns 'in line with the printing position. (2) Mechanism for 'shifting the type Vwheel around its axis through the space of a single column to bring an even numbered character column in line with the printing position. (3) Mechanism for inovingthe type wheel longitudinally to bring any horizontal row p f characters in line with the printing posiion. l

In addition to the above, I have devised and employ means for spacing between characters, for feeding the paper, for restoring the type wheel Ato its normal position at any point of its line of travel, for restoring the type wheel to its initial position to begin a line, and for effecting the other operations incident to apparatus of this character, all o f which from the nature of their construction and function may be best described by reference to the accompanying drawings in which- Figure 1 is a front view in elevation of the completely assembled elements making up the improved instrument. Fig. 2 isl a side elevation of the same, as viewed from the left of Fig. l. Fig. 3 is a top plan and part sectional view of the complete device. Fig. 4 is a vertical sectional elevation looking toward the right of Fig. 1. Fig. 5 is a similar view looking toward' the left of Fig. y

1. Fig. 6 is an end elevation looking toward4 the left-of. Fig. l. Fig. 7 is a sectional detail on the line 0f Fig. 6. Fig. 8 is a view in elevation of parts associated with the magnet which controls the impression devices. Fig. 9 is a diagranrmof the circuit connections showing the relations of the several instrumentalities. Figs. 10 and 11 illustrate details of .mechanism shown in eleva-V tion in Fig. 2.

The various parts comprising the apparatus are attached to and supported'by a substantial frame composed'of a base plate l, and side plates 2, B. Extending horizontally between these plates in the upper portion ofthe instrument is a paper feed roller consistingfof a shaft l carrying at its ends cylinders''g'l, having roughened or rubber faces, and intermediate vdisks 6, (l. Presser rolls 7, 7 spring actuated and car.- ried by arms pivoted to a shaft'S bear upon the roughened surfaces of the cylinders 5, 5. The paper from a suitable' supply reel is carried upward aroundguide rollers or disks 9, supported by spring actuatedarms 1 0, then between the platen and the type Wheel, hereinafter described, `..and `between theV presser rollers 'Y and the cylinders 5 by cross-section, and a rigid bar 16, in a slot in which projects an extension of tail piece 17 of the type Wheel carriage carrying at its end an anti-friction roller 18.v The spindle 14 passes through a triangular opening in a sleeve 19, see Fig. 1, which has a bearing in an arm 20 extending horizontally from the carriage 13. The spindle 15 in like manner, passes through a triangular opening in a sleeve 21 having a bearing in an arm 22, rigidly attached tothe carriage 13. The latter is thus held firmly against lateral movement, but is free to move longitudinally along its three points of support, which latter movement is imparted to it by a screw shaft 23 passing through a geared nut in a .projection Q4 on the inner` Asurface of the forward side of the carriage. Vertical movement is imparted to theftype Wheel by a rack-bar 25, sliding in guides on the carriage 13 and having a lateral arm 26 to which the type Wheel is connected in a manner not to interfere with its free rotation. A gear wheel 27, mounted lixedly on the sleeve 19,' and rotated by the triangular shaft 14, engages the rack bar 25 and when turned, raises the latter and With it the type wheel, to a position corresponding to the extent of rotation of the gear wheel. Rotary motion is imparted to the type wheel by a beveled gear Wheel Q8, mounted on the sleeve 2l and meshing with a beveled pinion 28, secured to the lower end of the spindle 1Q carrying the type wheel. The gear 28 is turned by thc triangular shaft 15, and the extent of rotary movement imparted to the type Wheel thereby corresponds to the arc through "c ich said shaft is turned.

ln the type Wheel carriage there are mounted two horizontal and parallel sliding rods 29 secured to and supporting an upright 30, provided with notches corresponding in position to the live vertical positions of the type Wheel. Extending horizontally from the upright 30 is a rack bar 31 in gear with an elongated pinion 3Q, journaled in the side plates 2 and 3 of the instrument. A fork or pawl 32, carried by a spring actuated bolt 33, sliding horizontally in guides on the arm 2G is forced forward by a movement of the upright 30 into engagement with a ratchet wheel 34 on the type lwheel, and at the same time its beveled end seeks the lowest point in the adjacent notch in said .the type wheel.

upright, so that the type wheel during such engagement is locked against both rotary and vertical movement and with a given selected character exactly in the printing position.

A. sheet metal plate 35 is secured to the carriage 13, and extends upwardly back of Near its upper end this plate is bent and. perforated. as shown at 36, Fig. 4, so as to expose a portion of the raised characters on the type Wheel. This o ening defines the printing position, and to e 1ect an impression from any character type that maybe presented at such opening a platen 37 extending across the instrument and mounted by arms 38 on a rock shaft 39, is oscillated' at the proper instant and caused to force the paper against the positioned character type.

From the above description it will be seen that it' the type Wheel/be rotated in its initial position, shown in Fig. 4, all of the characters in the upper row may be brought successively to the printing positionpand that if, either with or without rotatim, as the case may be, it be raised to aline the four lower rows of characters with the printing position 'any other character on the Wheel may be brought to the proper point for impression. It will be further observed that the devices which rotate and raise the wheel -maybe operated independently and either successively or simultaneously. It remains, therefore, to describe the mechanisms which effect or control the operation of these devices.

Referring to Figs. 6 and 7: An electra magnet or double solenoid 40 is secured to the side plate 2 and provided with a plunger or long stroke armature 41. A vertical slide rod 4'2 is connected at its lower end With the yoke of the armature by a spiral spring 43 and head 44, its upper end being pivotally connected to an arm 45 of a rock s aft carrying a toothed segmental arm 46. A spiral spring 47 tends to raise the arm 4G and depress the rod 42. The segmental arm 46 engages with a pinion 48 on a short shaft 49 (see Figs. 1 and 3) having bearings in the side plate 2 and a bracket arm 50 secured thereto, respectively, and when the magnet 40 is energized the raising of the rod lig/land swinging of arm 4G rotates the shaft 49 and with it the triangular spindle 14, which, although journaled on pointed pivot screws, is connected to shaft 49 by means of a spring dog 51, secured to the shafts 14 and 49, respectively` as shown in detail in F ig. 3. This connection is typical of any form of yielding connection which will transmit the rotation of one shaft `to the other accurately, but without shocln' The operation of these devices. as. has been stated above, resuits in a lifting of the type Wheel, the extent of lift obviously corresponding to the cured4 to the side plat/e2 is a U-shaped bracket 52 to the lower arm of which three' blades 58, 54 and 55, are pivote-d Side by side and extend upward through-a slot in the upper arm. Springs 56 act lupon the said i blades tending to maintain their upper end in engagement with the forward or outer side of the slotthrough which they project. A fourth blade or stop 57 of the full width ofthe slot is ixeldly secured to the bracket for a purpose t bel described. Three electro-inagnets 58,?? and 60, are mounted on the side plate 2,` nd each is provided with an armaturel carrying a finger, the end of which is adaptedto engage with and oscillat-e one of the blades when its magnet is energized. A rack bar 61 mounted to slide horizontally yin suitable guides on the side plate 2 is 'engaged by a. pinion 62 on'the shaft 49 so that whenthe magnet 40 is en-V ergized and the arm Ll6turned, the rack bar' 61 will be `forced forward to a corresponding extent' Normally, the blades 53, 54e and 55, -lie orteil-the path vof movement of the rack anni, which pani is iimnea only by the Vfixed stop 57, but when one of the magnets 58, 59 or 60 is energized, the blade crresponding thereto is'shifted into the path of the rack lbar 61, thus limiting the throw of the latterito less than the normal. These parts are so proportioned that when one of the magnets 58, 59 or'60 is energized the rack bar 61 operated by the solenoid 40 completes itsfull normal throw andraises the type wheel to bringvits lowermostrow of i characters inalinement with the printing position. If, on the other hand7 any one of the said magnets. as be energized, then by the interposition of the blade 55 in the path of the bar 61 the type wheel will be .raised butthiee Steps, instead of four, and

so on. Turning now to the opposite side of the instrument, there vis mounted on plate 3 a double solenoid magnet 63 with a long throw armature and a sliding bar 64; spring connected therewith, these elements being practical counterparts of the magnet 40 and its appurtenances above described. yThe bar 6ft operates, in like manner, a segmental arm 65 against a vspring 66 which transmits rotary motion through a short shaft 67 to the triangular spindle 15. A rack bar 68 is also reciprocated by a pinion on the shaft 67 and limited in its throw by four blades, one fixed and three movable, the latter engaged re spectively by thearmatures of three magnets 69, 70 and 71, and from the foregoing it will be understood that if none of these magnets is energized the'rack bar 68 completes its full throw and the type wheel is turned through eight-tenths?- of a complete revolution from its initial position of rest.

The energizing of magnet 71 limits the movement of the type wheel to six-tenths, of magnet 7 0 to four-tenths and of magnet 69 to two-tenths of a. revolution. rllius, by means of the devices just described any one of the live odd numbered vertical columns of characters on the type wheel may be brought into alinement with the printing position. To bring any of the intermediate or even numbere'dcolumns of characters into posi. tion to print, the type Wheel is advanced or shifted horizontally through the space of one vertical row from either its initial or any position to which it may be turned by the magnet.: 72, and this operation may be effected either before, aft-er or during the operation'of the magnet 63, and its appurtenances-by a mechanism which is best shown in Fig. 2. This comprises a` solenoid magnet 7 2 with an armature 7 3 supported above and partl out ofthe Vc oils by a spring seated rod 4.* When, therefore, the magnet is energized the rod 74 is forced downward. To the lower portion of the'r'od is secured a block 75 with a beveled face against which bears a roller 76 on a stud mountedl on a bar 77. The blades 53, :Stand 55, which limit the movement of the rack bar 61, that lifts the type wheel, havebeen described as pivoted to a stationary bracket, but the corresponding blades which limit the` movement ofthe rack bar 68 that operates to turn the type wheel, are pivoted to a sliding frame to which the bar 77 is attached, so that when magnet 72 is energized, this frame will be shiftedby a spring 78, toward the left, Fig. 2, but not sufficiently to carry the bladesout of the path of their appropriate armatures.

-The rack bar 68 carries a bar 79 with a toe 80 that engages a stop on the sliding frame so that when the latter is shifted the 4vrack bar will be carried forward correspondingly, a distance which is just sufficient to impart to the triangular spindle 15 a movement that advances the type wheel onetenth of a revolll@ lution, or through the space occupied by a' single vertical volumii of characters. VTo print, therefore, a character in the first or initial row, or the third, fifth or any odd numbered row, magnet 63 with either none or one of the magnets 69, 70, 71, is operated. To print from the second row, the magnet 72 alone is energized, or to print from any other even numbered row the magnet 63 with either none or one of the magnets 69, 70 or 71 is also energized.`

ln addition to the instrumentalities above -lset forth for setting the type wheel to print any desired character thereon, I employ various other devices which'are necessary or desirable in the operation of the instrument..

One of these is a means for locking the type wheel when adjusted to position and immediately prior to the operation of printing' acharacter. This comprises an electro-niagiat net or solenoid 81, armature 82, and rod 83, connected thereto, that operates to oscillate a pivoted arm 84. carrying a segmental gear that meshes with the elongated pinion 82, heretofore described. The operation of the magnet 81 is so timed that the type Wheel is set in position before the rack bar 31 is forced forward to bring the upright 30 in engagement with the locking bolt 33.

Another accessory is the means for advancing the type wheel carriage step by step after each impression, to space for characters. This comprises a beveled wheel 85, mounted on a shaft 86, andgearing with a beveled pinion 87 on a short counter-shaft 88, carrying at its opposite end a beveled pinion 89 meshing witha similar gear 90 on the screw shaft 23. The gear wheel 85 is rotated step by step by means of a ratchet wheel 91 on the shazt't 86 with which engages a pawl 92 carried by a pivoted leger 93 which is operated by engagement withl a bar 94 sliding in guides under the base plate of the instrument and connected with the armature of a feed magnet 95. `With each movement of the armature of this magnet the type Wheel carriages, through the gearing described, is advanced one character space, and in order to provide for the return of the carriage 'from the end or any other point in a line, the shaft 23 is extended to project through the side 3 ofthe instrument, where it carries a pinion 96, meshing with a barrel 97 that stores up the force of a coiled spring contained therein and operates to rotate the shaft 23 backward when the latter is 'released. This release is effected by a magnet 97, haring a spring actuated armature 98 connected by ay rod 99 with an arm 100 fixed to a short rock shaft 101 carrying a retaining pawl 102 engaging with the ratchet wheel 91. Normally the pawl 102 rides over the teeth of the wheel 91 as the latter is ade vanced7 but prevents its backward movement. When, however, the magnet 97 is energized thc pawl is lifted from wheel 91 and the type wheel carriage is brought back toward the starting position. In order to insure a complete return of the carriage, a spring actuated lever 108, pivoted to the side plate 3, is made to bear against the side of the free end of the pawl 102. A shoulder 104 is cut in the lever 103 and with this the against the selected and positioned character on the typewheel. The rock shaft 39 carrying the'platen may be operated for this purpose by a special magnet, but inasmuch as the locking of the type wheel must always precede the operation of printing, the movement of the means Jfor ettecting the locking of the wheel is conveniently availed of for operating the platen. 1 accomplish this by the means shown in Fig. L1. A rod 106 is mounted to slide in guides on the side plate 2 and carries a rack bar 107, that engages with the pinion 32. The reed 106 also carries a'stop 108, adjacent to the piaten 37, so that When the pinion is rotated by the magnet 81 and segmental arm 84, the rod 10G is pulled'forward, thereby engaging the platen through the stop 108 and fqorcing it against the paper.

The paper is -fed for line spacing by an electro-magnet 109, the armature of which operates a. pawl 110, engaging with a ratchet wheel 111 on the shaft 4, through the instrumentality of a spring actuated lever 112, a connecting rod 113, and apivoted lever 114 carrying the 'said pawl 110, as shown in Fig. 5.

Each of the mechanisms heretofore described as' the means for effecting the vari` ous operations necessary for adjust-ing and locking the type wheel, securing the 1mpressions, advancing the type wheel carriage for character spacing, returning the carriage and feeding the paper for line spacing, might be included in a separate and `independent circuit and the instrument operated by completing the circuits at the proper intervals of' time. Practical considerations, however, due in part to the relations which certain of the' operations bear to each other, render it desirable to provide special means for the operation and control of the various mechanisms and in i? ig. 9 the means which I have devised for this purpose are shown in diagram.. Before proceeding to a descrip.- tion of the diagram, however, it is necessary to explain the construction and function of certain devices not heretofore referred to.`

In Figs. 1 and 3, two small electro-magnets, 115 and 110, shown as mounted on the base plate 1, are provided with spring actuated armatures, 117 andll, which eon- :mensen carrying a contact spring 124, and forces'the latter against a Xed'stop 125 in its path,

I and thereby completes an electric circuit.

. downward through the base of the instrument, and engages the end of an arm 131, ona rock shaft 132, mounted in bearings on and underneath the base plate 1. When the magnet 126 is energized-it acts to depress the arm 131 and impart to the rock shaft 132 a partial rotation against the force of a spring. Another arm 165, fixed rigidly to the rock shaft 132, lies immediately under the end'oi" the rod 83 et' magnet `81 which locks the type wheel, and is depressed Whenever said magnet 81 is fully energized. The rock shaft 132, therefore, will be partially turned by the operation of either magnet 126 or magnet 81, but from the nature of the connections shown it' is evident that its movement by one magnet will not be inten tered with bythe other. tending rigidly from the rock shaft 132, rides against a spring actuated latch 134,

,pivotedfto theiunder side of the base` 1y as lshown in 'Figsl andy 1. so that when the rock shaft is turned. and the arm 133 depressed, the' latter is engaged by the latch and held down until released by thejwitn drawal of the latter. Such release is effected by a pivoted lever 135 engaging at one end with the latch 134 and at the other with a stop 136 on the rod 94, which, 'when shifted by the magnet 95, operates to advance the type Wheel to space for characters. On the forward end of the roek'shaft 132 is an arm 137 extending upwardly through the base plate 1 and carrying at its end an insulated stud 138. In the path of this stud are tivo normally separated contact vlevers 139 and 140, which by the engagement of the stud with lever 139 are brought togetherto com'- plete an electric circuit.

In Figs.4 2 and 5 a device for changing `the paper feed from single to double line spacing is shown. This consists of a bent lever 141, pivoted to the side plate 3, and having a stud that projects through a slot insaid plate-and lies under onearm of the bell crank lever 110 constituting the pawl that engages With `the ratchet Wheel 111 of the paper roll. The lever 141 is acted upon w by a spring actuated lever 142, having a cam projection 143 to hold the first named lever in either of its tWo normal positions by engaging with a. pin 144 lthereon. By shitting the lever 141 the throw of the pavvl is varied in a manner that is Well understood.

Referring 4novv to Fig. 9: A plurality of localcircuits is provided in the instrument by the proper number and disposition of in- An arm 133, eX-V sulated conductors and terminals, the latter in the commercial instrument, being conveniently placed on the base plate- 1 in the rear of the Working parts. I have shown nineteen of these terminal plates, but a greater or less number may be employed if desired to meet special conditions or eiiect special results, and to distinguish them they are numbered consecutively from 145'to 163. From each of the terminal plates 146 to 159 inclusive, a circuit connection or Wire is shovvn, which, if carried to ground, Will effeet the operation hereinafter described. These connections, to correspond with those of the translator, are designated by the letters c to n, respectively. The terminal 160 is shown conventionally as directly connected te earth. Assume then, for the purposes of illustration, that a battery 164, or other local source of electrical energy for the operation of the instrument, is connected to the terminal plate 14.5 and to ground, respectively. It follows from the circuit connections and apparatusillustrated that if plate 146 be grounded, acurrent starting from "battery 164 will pass to the magnet' 115, thence through magnett, thence through magnet 69, and thence to ground through terminal plate 146. From previous explanations it will be understood that the result will be the operation of the type Wheel",turning magnet, the drive or which will be limited by magnet 69, which acts somewhatzquicker, to one step or two column-spaces, and the character at the top of the third vertical column will be presented in the printing position. l't will also .result that magnet 115 attracting its armature 117 will close a branch circuit from the battery through timing magnet 120, which in turn closes the circuit of the type Wheel locking and printing `magnet 81, which latter by the depression of the rod 83 imparts a partial rotation to therock shaft 132, causing the latter to engage with latch' 134 and closing the contact between 139 and 140. This closure completes a branch cirsuit from thebattery to the cross-feed mag net 95 which in its operation of advancing the' type Wheel carriage'one step after the Vimpression has been taken, operates lever 135 and releases the latch engaging the arm 133 of the rock shaft; This completes the operation, the' type Wheel having received a turning movement of one step or twoucolumn spaces, the character printed and theacross-y feed eti'ected. f

It is required inthe system for which this instrument was designed and with which it, as organized according to the above description, is intended td be used, that, after each operation, effected by grounding any one or more of the terminal plates, a path for cur-v rent to an eleetro-magnet in another part of the system be closed,l bringing about what is known as the clearing lof' the instrument which controls the operation of the printing apparatus. y y. y

1t has been explained that Whenever either the type wheel locking magnet 81, or the; timing magent 120, or both, are energized, the Contact points 139and 1'40, Fig. 1, are brought into engagement and so maintained. by the arm 133 engaging with the latch 134. This operation closes trhe circuit from the battery 164 to ground through the cross feed magnet 95, which, at the end of its operation, releases the latch 134 and breaks the circuit between points 139 and 140. It will be observed, however, that by completing the circuit to ground through magent 95, the battery 164 is also connected to terminal 155, which latter is arbitrarily selected for the circuit that includes the clearing magnet above referred to, and which is therefore operated whenever the cross feed magnet 95 is energizbd. It will be further observed that when the paper feed magnet 109 is energized, either alone, or in conjunction with other magnets of the apparatus, it operates through the instrumentality of any suitable connection, such as shown in Figs. 3 and 5, a circuit controller 167, which connects the batery 164 with terminal 155. Thus it follows, that Whatever devices may be included inthe circuit continued to ground from terminal 155, they `will be operated not only when the cross feed magent 95, but also when the paper feed magnet 109 is energized. Iii terminal plate 147 be grounded the same operations Will take place except that magnet 70, instead of 69, is energized, which results in the type Wheel being turned to an arc including four character column spaces. In like manner, the groundingotl terminal 148 brings the seventh column on the type wheel into printing position, and so on. The grounding of plate 150 causes. currentr to -liow through the type wheel shift magnet 72, which, as has been described, advances the type Wheel one column space,

- bringing the second column of characters to the printing position when no other turning movement has been imparted to the type Wheel. The grounding of terminal plate 151 causes current to pass to the driving magnet4 40 and also the magnet 58 which lifts the type wheel one step or stage and brings the second row of characters to the printing position, all of the other operations hereto- 'fore described, except that effected by the type Wheel shift magnet, being repeated. In

like manner the vgrounding oi. plate 152, lifts the type wheel to bring thel third horizontal row of characters to the printing position, and so on, and from-the description of the apparatus heretofore given it will be evident that any tivo or more or the above described operations may be elected simultaneously. That is to say, by grounding the proper terminal plates the type Wheel may be simultaneously lifted, turned and shifted, to bring any desired character thereon into position to be printed. Terminal 155, as has been above stated,.is arbitrarily selected to complete a-path for current to pass to the clearing magnet in another part of the circuit at the same time that it also passes from the battery to the cross feed magnet. 1f the terminal plate 156 be grounded, the current passes to control magnet, 116, which closes the circuit throughmagnet 127 which latter, as above described, closes the circuit to the cross feed magnet by bringing together the contact points 139 and 140, and effects no other operation besides spacing except that of clearin. If terminal plate 157 be grounded, 'the paper feed magnet 109 alone is operated so that the paper may be fed line by line without actuating any of the other devices. lnasmuch as this operation however requires the transmission of a clearing curent the magnet 109 operates a circuit closer 167 which completes the battery connection to plate 155, which circuit is interrupted by a cessatioli of the current impulse through the paper feed magnet. It terminal 158 be grounded, the magnet 97 that releases the type wheel carriage and permits it to return to the position to begin a line is operated.' The closureof this circuit how:n ever also energizes the paper feed magnet 109 which in turn closes a circuit to terminal f 155, i'vhereby the clearing operation is eected. When contact plate 159 isv grounded a path for the current is completed from the battery through control magnet 116, and a signaling device 166, which is used for ytransmitting to the sending operator at the receiving station 'a conventional signal. Control magnet 116 completes a circuit through the magnet 127, by means of which the clearing operation heretoforedescribed is edected.

Terminal 160, While not so marked, is a 'general ground for the apparatus and wherever, the conventional lines indicating a ground are used, connection with the terminal plate 160 is assumed. Terminal plates 161, 162 and 163 are in practice utilizedl for purposes which have no direct bearing on the -features of novelty upon which the Ipresent a plication is based, and require no further escription herein.

Il It will be noted that the circuit of con- I ing and printing magnet 8l operates the ci cuit controlling contacts 139 and 140, Whil ground is lifted from whatever circuits ment` the combination with a type-wheel, a Y
